"The objectof this i ivention is t'ojdevise a novel andimprovedcons'truction ofa rotatably mounted vending drum for coincontrolled vending machinesof the type dis-3 closed in the FritschePatent No., 1,039,508,

patented September 24th, In drums of this type they are preferablyconstructed sothat a number of superimposed compartments are provided,each having a single opening thereto.

When the drum is init'svendingposition these openings serve as deliveryopemngsu and, accessto them by the purchaser 1S'COI1- the door beingmountedjin suchia manner that when so released it will partially open;

When the drum is rotated to bring the I openings to the rear, suchopenings serve as filling openings for the articles to be vended.

7 It has been found fromthecommercial use of vending drums of this typethat the construction can be materially improved to enable it to be themore readily manufactured, to: increase its durability; and to provideinany advantageous features which were not present in priorjdevices. e j

'It'has been found desirable to illuminate the articlereceivingcompartments when they are in vendingf'positiom-to provide thedrum with means to limit the opening move r .ment of thedoors,andtoprovide means to prevent the rotation of the drum'by the :atp 7'ing drum'in' detached position and its nontendant in rate of themachines when any of the doors are'insuificiently closed in order toprevent injury to the intendingpu'rchaser 'by his hand beingcaught bythe door.

In so doing, it exerts a pull on the link 38thereby actuating the slide 37in a position to rock the levers 32 andcause the locking plungers to become disengaged from thewalls oftheopening 31 in the bottom of a door 2.

i The purchaser can now open the door- 2 and bodies the features ofadvantage enumerated V remove from its article'compartment, the ar ticlewhich he haspurchased.

When the attendant wishes to refill the vending drum, he takes hold ofthe grasping handle 26 and rotates the drum 5 in a counter clockwisedirection. If the door 2 is not sufiiciently closed, the stop portion 19of the cam 18 will prevent the rotationof the drum so that unless thedoor is sufliciently closed to prevent any one inserting his handbetween the door and its door casing, the vending drum. cannot berotated.

When the doors 2 are sufficiently closed the roller 7 rides up on theincline 21, and engages the outer periphery of the cam 18so that thedoor is forced into its locking position, and

as soon as the cam 22 engages the roller car ried by the lever 42, thelever 39 operatively.

connected with it is rocked, thereby actuating the slide 37 to move theplungers 20 to locking position and effecting the locking 0 all of thedoors to the compartments. I

When the vending drum is in its vending position, the cam 22 engagesthelever 42 and moves it outwardly so .that a stop member 44 whichextends into the coin chute can be moved outwardly of such chute topermit the coin to pass freely therethrough in a similar manner to thatdescribed and broadly claimed in my co-pending application for coincontrolled vending machines,

The stop 29 cooperates with fixed portions of the framework so that whenthe drum is rotated in one direction it will stop in its vendingposition and when rotatedin a re this embodiment is susceptible ofmodification in various particulars without departing from the spiritorscope of the invention or sacrificing any of its advantages.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is
